HHY Language 1.3.1

HHY v1.3.1

HHY v1.3.1 hardens the opt-in Bytecode path against official real workloads
without changing the frozen language contract or the AST default.

Real-workload compatibility

• Adds make workload-test and a machine-readable workload evidence report.
• Runs each selected official project self-test under both AST and Bytecode.
• Always validates the local Asset Governance filesystem workflow.
• On hosts with loopback socket capability, also validates DataFlow ETL,
  FlowGuard, Hong Kong Film Companies, Multi-API Data Collector, my-crawler,
  and SiteGraph Auditor.
• Preserves every project's existing report assertions, expected failure paths,
  dry-run behavior, extension usage, cancellation, and resource boundaries.

CI integration

• Linux arm64/x86_64 and macOS arm64 release suites run the real-workload matrix.
• The release workflow runs the same matrix before archives can be published.
• Capability-based skips are recorded explicitly instead of silently passing.

Compatibility

• hhy run remains AST by default.
• hhy run --engine bytecode remains source- and diagnostic-compatible.
• No Bytecode disk format or public ABI is introduced.
